Document Summary
Muscle that is under conscious control of ns. Involuntary muscle under control of the autonomic ns. Surrounds fluid containing vessels such as stomach, intestines, glands. Movement: contraction of skeletal muscle causes an inhibits movement. Protection: abdominal muscles protect abdominal organs; muscles around your mouth and eyes can can close for protection of underlying tissue. Maintain body temp: contraction of muscle produces heat. Isotonic: the muscle shortens or lengthens during contraction: Concentric: tension in muscle as muscle is shortening. Eccentric: tension in muscle in lengthening, usually force that causes the movement is gravity. (muscle is lengthening under tension to control the movement caused by gravity). Force: muscle or gravity is the force; force is applied to the moveable bone in the system. 1st class: like a seesaw: has the fulcrum in the middle and the weight and resistance on either side of the fulcrum. Force: posterior muscles attachment to the base of occipital bones.
